    Compensated Neutron Log

    A compensated neutron log is useful for identifying zones of interest and determining perforating depths, tracking gas cap movement and gas encroachment under shale layers, as a correlation between open and cased hole where a gamma ray is not indicative, and to measure overall porosity of the well. At Renegade we primarily use the compensated neutron log (CNL) to identify pay zones in a well. Once the zones of interest are identified and logged, the engineer can make an informed decision on perforation placement.

    Gamma Ray Log

    The Gamma Ray Log measures total natural radioactivity and is displayed in American Petroleum Institute (API) units. The measurement can be made in both openhole and through casing. Shales and clay are responsible for most natural radioactivity, so the gamma ray log is often a good indicator of such rock. The log is also used for correlation between wells, for depth correlation between open and cased hole, and for depth correlation between logging runs.

    Spectral Gamma Ray Tool

    Spectral Gamma Ray Tool provides information about the mineralogy of formations, specifically the source of a particular gamma ray by measuring the amplitude or energy level. Since the most frequent sources of natural radiation in the formation are thorium, uranium and potassium, the tool can measure the amount of each in shale and sand formations.  

    • Provides detailed stratigraphic correlation 
    • Identifies depositional environments 
    • Determines clay type analysis and volume 
    • Heavy mineral identification 

    The tool utilizes a large, ruggedized scintillation detector to measure the quantity of naturally occurring potassium, uranium and thorium. The total gamma spectrum is resolved into 256 channels internally and used to determine the components of naturally occurring radiation in sands and shales. This data is used to distinguish important features of the clay or sand around the wellbore formation such as clay volume, clay type, heavy minerals and is also used for fracture detection.

    The detector package is designed to maximize the energy spectra sensitivity over the entire range of energy levels and logging speeds encountered in various formations. The tool uses an automatic internal stabilization circuit to stabilize the detector and electronics for temperature drift errors over the entire operating temperature range.

    Injection Profile Logging (IPL)

    Fluid Flow Data From Injection Wells Provide Insight on Overall Well Construction Integrity

    As a field matures the need for injection profile data from injection wells increases. Running injection profiles eliminates assumptions of fluid direction providing an overall view of well performance and integrity, allowing operators to map their water or CO2 flood.  

    Renegade Injection Profile Logging (IPL) checks the integrity of overall well construction on injection wells. Profiles are run to determine the health of injector units, monitor fluid dispersion, find and measure out-of-zone losses and provide a comprehensive picture of the overall downhole activity on an injector. This service can identify leaks out of the zones’ injection area, including packer leaks and holes in tubing where there are no perforations.

    The shut-in portion of the injection profile log can provide customers insight into areas of fluid storage and communications between high- and low-pressure zones. Renegade’s injection profiles provide the confidence to efficiently tackle problem-well situations that can commonly cost much more and take longer to complete. Services are typically run every four years for water wells and two years for CO2 wells. 

    IPL has two advantages over traditional mechanical services such as spinner tools. First, it can observe fluid movement behind pipe; second, they eliminate the risk of blades sticking if wellbore debris is encountered. In some instances, RA tracers may be the only way to identify and locate problem areas in the well. Renegade utilizes innovative equipment and tools and has an in-house RA lab to mix RA material for specific volume and job needs.

    Production Logging Services 

    Critical Data to Help Maintain Well Performance

    Production Logging services evaluate fluid production rate and flow in producing wells and are a main indicator of well performance and problem identification. The results of a production logging services help recommend remedial treatment or workover operations.  

    Renegade Production Profile Logging has proven to be the most reliable logging technique to give operators qualitative and quantitative evaluation of injection fluids and to aid in the evaluation of the performance of field floods.  

    The same technique can be reversed for producing wells. Radioactive tracer surveys ran in conjunction with other surveys, such as temperature gradient, capacitance, velocity, bottom-hole pressure, fluid density and calipers, will give the operator a full complement of surveying techniques to help fully evaluate their wells.  

    Applications 

    • Locate oil, gas and water entry 
    • Fluid flow: no-flow check and cross-flow check 
    • Shut-in cross-flow check 
    • Injection profile log: pump-in tracer, channel-down check and CO2 composite 
    » Renegade designs the optimum production logging job with the right tools and equipment.

    While many companies may provide this service, only Renegade has the knowledge to perform a successful job every time. 

    Renegade Services has several production logging supervisors with over 25 years’ experience running production logging services. Our team will work with the operator to help ensure a safe, successful job, completed in the least amount of time.  

    • Select the right tools and equipment 
    • Make sure pressure control equipment is on location 
    • Review all well conditions such as temperature and pressure 
    • Weight bars and backup tools are available if needed 
    • Selection of radioactive isotope 
    • Safe operating procedures for handling and storage of radioactive materials  
    Step-Rate Tests

    Obtaining data is the key to planning a successful frac job. Step-Rate tests are one method for estimating the maximum injection pressure, one of the most useful parameters when planning the optimum frac treatment.  

    A step rate test can accurately measure the injection pressure needed to fracture a formation when planning a hydraulic frac job. During the test, fluid is injected into the formation at increasing pump rates. As each rate stabilizes, injection pressure data is taken for each rate. The resulting data is used to create a plot displaying injection pressure verse injection rate. From this plot, pressure and flow rates can be established to identify the fracture pressure necessary to fracture the formation and successfully place fluid and proppant.  

    Spectral Noise/Digital Temperature Survey

    The relationship between reservoir flow and wellbore flow is critical to well performance. The Renegade spectral noise log in conjunction with a high-precision digital temperature survey can accurately locate and quantify reservoir flow and wellbore flow to help determine the relation between the two.   

    This combination can diagnose unexpected well problems and also proactively ensure the well is working properly. Resulting data provides a wealth of information on well performance and can help identify zones where remediation is needed.  

    • Identify surface casing vent flow (SCVF) 
    • Identify external gas migration (GM)  
    • Identify fluid flow behind multiple casing pipe barriers 
    • Locate source of downhole leaks 
    • Help identify leaking fluids into freshwater reservoirs  
    • Identify regional lateral flows and crossflows 
    • Differentiate fluid and gas flow and amount 
    • Identify annulus leaks for sealing with Renegade Local Expander technology so P&A can commence

    Renegade can use bond logs and casing inspection logs to identify, map and further explain spectral noise/digital temperature survey data.  

    Renegade Memory Gauges

    A producing wellbore creates a tremendous amount of information that must be gathered, managed and then interpreted. A variety of diagnostic tools can help you manage the production of your well and gain valuable insights into the processes that are occurring downhole. These tools provide the data that help operators to identify what systems to use to increase or maintain production and how to adapt to changing conditions of the wellbore. 

    Memory gauges are one of the most helpful tools for well diagnostics. They detect and measure temperature and pressure at points along the wellbore. These gauges are beneficial because they provide downhole information without requiring substantial resources.

    They also eliminate the need for deploying e-line each time temperature and pressure measurements are required.  Memory gauges are powered by a battery pack and can be set downhole and left for an extended period to capture and store data and then be retrieved at a later date. 

    • Data can be used to determine the flow rate of the well 
    • Provide information to help implement the right lift systems to maintain production  
    • Help devise a cost-effective and timely program to monitor and maintain the well production

    Cement Bond Integrity and Evaluation 

    The Renegade Difference 

    Along with casing, cement is the backbone of the wellbore. A good cement job protects the formation and the water table, prevents leakage from the wellbore into the formation and provides the structure that supports the completions hardware. It is one of the most critical components of a producing well.  

    Renegade provides services that monitor the health of the cement and cement bond to both formation and pipe. Our tools identify problems that could ultimately affect well integrity. If problems are found, we can recommend and carry out immediate remediation services that can prevent greater failures if not addressed.  

    • Unmatched data quality with over hundreds of data points per foot, even at logging speeds over 100 ft per minute. 
    • Shorter tool lengths reduce the risk of damage to the wellbore or the environment.
    • Provides cement evaluation, casing wear and casing thickness information, corrosion imaging and fluid properties in the wellbore. 
    • Identifies micro-annulus to shut off service casing vent flow. 
    • Can log environments up to 350°F and 20,000 psi. 
    • Tools can be combined to run in stack configurations (cement bond, gamma ray, CCL, caliper, magnetic thickness) for greater time savings on workover and drilling rigs.

    Radial Cement Bond Log

    The radial cement bond tool utilizes a single ceramic transmitter, an eight-segment receiver at 3-ft spacing and a single receiver at 5-ft spacing to accurately measure the quality of the cement job in a cased hole well environment. The segmented receiver provides a good indication of cement channeling behind the casing.
